Hatestrument is a room-sized instrument designed as a collaborative experience. The visitors make music with hate messages from the internet in order to transform them into something positive. 
It has a circular sequencer projected on the ground so when people step on the right spot, a word of the hate message is played and the music starts. The area is surrounded by dozens of transparent screens displaying the words that the people play. The goal is to play all the words of the hate message in the right order while putting them in a new musical context. I created the vision for this installation and guided my team through 3 months of development as the director and game designer.
